Ball lightning is a phenomenon that continues to baffle scientists the world over. Its volatile and dynamic nature make it practically impossible to place under a microscope for closer scrutiny. Researchers are forced to rely on laboratory simulations to catch a glimpse of its fascinating behavior. While the scientific community has learned a great deal about the phenomenon, researchers have still been unable to replicate the anomaly. Naturally occurring ball lightning doesn’t rise, and every replication attempt has resulted in a manifestation that does.

The stone spheres (or stone balls) of Costa Rica are an assortment of over three hundred petrospheres in Costa Rica, located on the Diquís Delta and on Isla del Caño. Locally, they are known as Las Bolas. The spheres are commonly attributed to the extinct Diquís culture and are sometimes referred to as the Diquís Spheres. They are the best-known stone sculptures of the Isthmo-Colombian area.

The spheres range in size from a few centimetres to over 2 metres (6.6 ft) in diameter, and weigh up to 15 tons.[3] Most are sculpted from gabbro,[3] the coarse-grained equivalent of basalt. There are a dozen or so made from shell-rich limestone, and another dozen made from a sandstone.
